Bug #675
Exif extraction fails under certain cicumstances
100%
Description
I have at least one JPEG that has valid exif data that can properly be retrieved using Photoshop and ImageMagick, but not via Exiv2.

Most of the metadata in this image is XMP data, not Exif data. Photoshop and apparently also IM convert it on the fly or at least don't clearly show the type of metadata. The standard summary output of exiv2 on the other hand looks only at Exif data, which is why it doesn't show much. This is what I get with the -pa option:
